HUsroN, or sHnLn vrLLnJLLInoIs, ASSIGNdR, F own-HALF ro WALTER G.HEADEN, OF SHELBYYILLE, ILLINOIS.

' citizen of theUnited States, residing at Shelbyville, in the county ofShelby and State, of Illinois, have invented certain new and usefulImprovements in F Inc-Stoppers; and I do declare thefollowing to be a full, clear, and exact description of the lllVGIltlOIl,

such as will enable others skilled in the art to which it appertains tomake anduse the same.

This invention relates Ito flue stoppers, and more especially to thatclass of the latter which employs a thin'nble in con unction with a cappiece.

One object of my invention resides in providing a flue stopper, and icap thereforl having'means cooperating wlth certain other means carriedby the flue stopper for withdrawing the latter from its seat, so thatall possibility of soiled hands and other annoyances usually areeliminated.

Another object of this invention resides in producing a flue stopper andcap which are efficient in operation, simple in construction, andparticularly Well adapted for the function hereinafter tojbe ascribed tothem.

With these and other objects in view my invention consists of certainnovel features of construction and the combination and arrangement ofparts as will be more fully described and claimed.

In the accompanying drawings Figure 1 is a fragmentary section of achimney with my improved flue stopper disposed" therein.

Fig. 2 is a vertical longitudinal section illustrating the means forremovingthe thimble.

Fig. 3 is a similar View taken at right angles to that of Fig. 2. Fig. 4is an end elevatlon of my improved stopper illustratmg my improvedlocking tongues. Fig. 5 is a transverse vertical section taken on theline 55 of Fig. 3.

Referring more particularly to the drawings, the thimble 1 comprises asheet metal I body :2 bent into cylindrical formand having its meetingedges brought into engagement and bent into anin'terlocking joint '3. Inorder to permanently close the inner,

end of the thimble 1, I slash the cylindrical body 2 around its edge soas to form a plu rality. of tongues 4. The alternate tongues 4 I bendinwardly and at right angles to the cylinder to provide a seat for thehead or closing member 5 which is seated thereon.

i would be subject to the disadvantage stated, the head 5 cannot dropfrom the cylinder and thereby destroy the utility of the inresultingfrom "this operation drawal of the same,

if The remaining tongues 6 are then projected Be it -k'nownthatl, THOMASH. Hios'ron,v

in a similar direction and brought into en- 1 the chimney with theclosed end adjacent the chimney flue, the head 5 must be securelyfastened by some means absolutely .un-

affected by heat; consequently by providing the" tongues as above setforth in place'of solder or other connecting means which vention bypermitting the dirt and soot of the chimney to enter the room.

A cap 7, having a diameter slightly greater than that. of the thimble 1,closes the outer end of the same, and when said thimble is placed inposition gwithinf'the stove pipeopenmg, it projects laterally beyond thead acent end of the latter, cover ing it completely as well aseliminating the l nsightly open end of the thimble, thereby rendering afinished appearance to the room.

To retain the cap ln'positionupon the thimble 1 as well as to facilitatethe ready with n I' strike the two diametrically disposed inwardlyprojecting tongues 8 from the outer edge of said cylindrical body 2,and-at a central point on the inner surface of the cap 7 I secure abowed leaf spring 9 which is intended to "project within said thimbleand'have its ends bear against the inner surface thereof and by itsresiliency hold the cap in position. In addition to maintaining the cap7 in powithdrawal of the thimble from itsseat, in-

asmuch as when cap 7 is partly withdrawn drawal of the cap will alsoremove the {thimble as will be readily understood without furtherdescription. Thus it will be seen that by providing the cap 7 inaddition to the head 5, the unsightly open end of the thimble is avoidedand means provided for the removal of the'thimble when it is de sired toreplace'the latter with'a stove pipe.

j with the tongues-8 so that furtherwithlit) sition, the tongues 8 alsoserve another pur-. pose, thatis, they provide means for the w Copiesof; this patent may be obtained for From the foregoing'it will be seenthat the thimble and cap therefor when inserted inthe; stove pipeopening thoroughly and practically close the same, and prevent'soot orfire from gaining access to the room.

Various changes in the form, proportion,

and the minor details of construction may be resorted to withoutdeparting'from the principle or sacrificinganyof the advantages of theinvention as claimed.

What is claimed as new is: v 1'. In a device of the character described,the combination witha thimble having a closure at the inner end thereofand pro-1.

-..vid ed-,,With inwardly projecting tongues disposed at opposite pointson its inner .sur-

face adjacent its outer end; of a cap closing theopen end of saidthimble, the outer edge of said cap extending laterally beyond "theouter end of the latter, and 'a bowed leafspring secured intermediateits ends to the central portion of said cap, the extremltles ofisaidspring extendingto and bearing against the sides of said thimble wherebywhen said cap is partly withdrawn andrethimble.

volved, said extremities wilhfrictionally engag'e said tongues for theremoval of said 2.
